Alternative TLS implementation in Go

Adam Langley 25dd71bbe6 crypto/tls: don't send IP literals as SNI values. https://tools.ietf.org/html/rfc6066#section-3 states: “Literal IPv4 and IPv6 addresses are not permitted in "HostName".” However, if an IP literal was set as Config.ServerName (which could happen as easily as calling Dial with an IP address) then the code would send the IP literal as the SNI value. This change filters out IP literals, as recognised by net.ParseIP, from being sent as the SNI value. Fixes #13111.
